Claims.

The present invention relates to looks for vehicles and particularly to locks for movable parts thereof such as the doors of a closed vehicle such as a "sedan type of automobile.

Heretofore, on such vehicles, in order to lock the doors thereof, it has been necessary to voluntarily lock each door. This is usually done by operating a button or lever on the inner side of the turning of the ignition switch.

A further object is to so look the doors that while access to the interior'is impossible, free egress is allowed.

A still further object is, to provide means for simultaneously unlocking all of the doors from the interior of the vehicle.

Another object is the means by which the preceding objects are accomplished.

In the drawing the invention is illustrated as applied to a door lock, for example, for a door of a closed automobile, and the drawing shows in Fig. 1 two door looks with the controls therefor; in Fig. 2 a section through line 2-2 of Fig. 1; Fig. 3 is an enlarged diagrammatic view of contacts 50, 54 in which the contact 50 isillustrated twice, once to the right of the contact 54 showing the relative position 01 these contacts as the ignition is being turned oif and the circuit through solenoid 35 temporarily completed, and once to the left of the contact 54 showing the relative position of these contacts as the ignition is being turned on: and Fig. 4- is an enlarged section on line 4 4 of Fig. 1.

As shown, the device consists of a lock having a casing 10 in which slides a bolt 11 carried in suitable guides, one of which is shown at 12. At the rear end of the bolt 11 is a cross piece or abutment 13 against-which is adapted to act a double cam piece 14. This cam piece has the two cam ends 15 and 16 so that it may be rotated either way and will operate the bolt and, further, is mounted on a square shaft 17 which extends through the cover for casing 10 and will be the shaft for a handle on the outside of the door- (the cover, handle, and door not being shown).

The inner end of shaft?! will be round as shown clearly in Fig. 2 and will serve as a bearing for the lower end of lever 20. The latter will have near its lower end on one edge a cam surface of a contour similar to or the same as that on cam 15 and will extend up to the upper edge of the door body so that bolt 11 may be operated by either the handle mentioned or the lever independently of the other. The round end of shaftl'i' will also extend. through a slot 21 in bolt 11, the shaft acting both as a guide and stop for the bolt, and will pass through the casing 10 and be secured in any suitable manner as by cotter pin 22. A suitable spring 23 will be used to return the bolt.

In addition to the parts mentioned, a second bolt or dog 25 will also be mounted in casing 10 in suitable guides 2,5 and 27 and this bolt is adapted to enter a slot 28 in the edge of cam piece 14 and prevent turning of the latter. Bolt or dog 25 will be impelled toward the slot 28-by a light spring 29 between guide 26 and a collar 30 carried by the bolt, and will be retained out of the slot by a latch 31 co-operating with a notch 32 in the bolt 25 when the latter issufliciently retracted. This latch 31 will be pressed into the notch by spring 33 acting against a plunger 34 which in turn acts against latch 31. Latch 31' and plunger 34 will be guided in and the former will act as the core of a solenoid 35. Latch 31 will be of magnetic materialwhile the plunger 34 will be of nonmagnetic material.

Further, there will be another solenoid 40 surrounding the rear end of bolt or dog 25 so located as to retract the bolt from engagement with slot 28 and a sumcient distance to permit .engagement of latch 31 in notch 32. r

In addition there will be provided in one of the locks a key operated barrel 41 carrying a finger.

42 acting on collar 30 to retract bolt 25 a suflicient distance to disengage slot 28, but being prevented.

by a stop 43 from retracting the bolt far enough to cause latch 31 to engage notch 32.

As indicated, solenoids 35 and 40 will be connected to the electric system of the vehicle, the former through any suitable switch as, for instance, a special ignition switch and the latter may be for example, through a separate switch 45 located at any suitable place on the vehicle, for example, a simple spring button switch on the instrument board.

Solenoid 35 will be connected to ground at one side and to a contact piece 50 in the ignition switch on the other. Contact piece 50 and the other elements of the switch will be so constructed and arrangedthat the circuit throughsolenoid 35 will be closed only during the operation of turning off the ignition. This may be done by the means indicated in the drawing. I

In a common type of ignition switch a disc 51 carrying three integral fingers 52, 53 and 54 is keyed or splined to a shaft 55 forming part of the operating lever (not shown). When this disc 51 is in the position shown in full lines, the fingers 52 and 53 are in contact with two contacts 56 and 5'? connected respectively to the ignition circuit and the battery, while the finger 54 acts merely to balance the pressure of the other two. In the dotted position, finger 53 is in contact with contact 56 but the othertwo are not making contacts and the circuit is accordingly broken.

For the present purpose contact 57 is extended laterally so that finger 53 maintains contact therewith after finger 52 has left contact 56, and contact 50 is arranged to co-act with finger 54 when the disc is moving in a counter-clockwise direction and before finger 53 has left contact 57. This may be accomplished by forming finger 54 with one edge turned up and the other down as indicated in Fig. 3 so that in turning off the ignition finger 54 passes over contact 50 and in turning on it passes under the thin 'piece of insulating material 60 upon which contact 50 is mounted, the numeral 80 indicating a depression below the insulating piece 60 permitting the action just described.

While the device has been described with reference to a single lock it is obvious that it may be applied to several locks on the same vehicle and this is contemplated. In fact, a second lock is indicated at 75 similar in all respects to the other except that it has no keyoperated part. A key operated part need be used. on but one of the locks on a vehicle because when one door has been opened, switch 45 is accessible to unlock all of V the doors simultaneously.

member described and claimed in Patent Nos 1,805,088, issued May 12, 1931, by the applicant" and such use is in contemplation. If this is done,

the mere voluntary stopping of the engine by turning off the ignition willlock the particular control member and all of the doors instantaneously so that it will be impossible for the operator to leave without securing the car against unauthorized use.

While the invention has been described as applied to door looks, it is not to be-considered as limited to this use. It may be applied with minor modification to any movable part, such as' the hood, a spare tire lock, tool-box, and so forth, any or all of which may be aranged to be locked when the ignition is cut off. It will also be apparent that the switch that controls the solenoids 35 need not at the same time control the ignition, but I regard the control of the locks by the ignition as desirable under some circumstances.

Having now described the invention and the preferred form of embodiment thereof, it is to be understood that it is not to be limited to the specific details herein described and illustrated but only by the scope of the claims which follow:
